Auction Details

We're sorry for the confusion that a lot of bidders have had. We don't take credit cards because they companies will charge us anywhere from 11-25% on the sale of firearms. It does take longer because we receive our items from our inventory of wholesalers and importers. This process does unfortunately delay the process of you receiving guns so please expect a delay in shipments.

Thank you
Worldcrest Auctions, Inc
Unless stated otherwise, Firearms are brand new, still in the manufacturers box. We open each box to insure the correct firearm is inside the box.
